Water injection is an accepted practice to keep combustion temps down (detonation) but as far as burning it, nothing short of actual hydrogen is currently used that I am aware of. Hydrogen is combustible and oxygen is an accelerant so if the atoms can be separated Katie bar the door.

Well a bunch of country boys sure proved them wrong. One of my co-worker's kid had a teacher who disputed it, until she made a miniature version as her high school science project. Blew all the nay-sayers out of the water. Pun intended.

Just for the record, the pursuit was called off for safety reasons, per the department's statement...
"Just before the pursuit ended at 11:13 p.m., the officer driving the Tesla responsibly notified his cover units he was going to have to back out of the pursuit because his battery was running low. Just after they passed the Montague Expressway exit, the suspect drove on the left shoulder of the road to pass a vehicle. At that time, the Fremont Police Sergeant monitoring the pursuit gave orders to terminate to ensure public safety. All three units deactivated their emergency equipment and returned to normal driving conditions."
Although the Tesla was low on juice, all three cars stopped pursuit at the same time. Tesla was able to drive to a recharge station on its own and charge up, as the other gas cars went back to normal patrol.

We had a waste oil / water drip heater at my former place of work.
One of the 'old timers' was showing it to me, and he said it was 'as if' the water itself burned. I was arguing with him, and he said he knew water wouldn't burn but it did.
I never got to see it work, we burned wood the 10 years I was there.
Never let the facts get in the way of a good story.
As for the water "burning" thing, whats more likely is the steam from the water drip onto the hot burner was causing some of the fuel to atomize which would make it burn faster. Also possible it was adding some cooling to the burner arrangement so it increased the fuel flow or air density or something.
I can see it now, the NASCAR BATTERY CUP SERIES. One pit stop for a fresh battery pack per race. One plus would be the noise, or rather the lack of it. You could locate speedways close to or inside most metropolitan areas.
If only NASCAR weren't dying.
Yet there is already Formula E racing - WAAAAAAY ahead of NASCAR

oh, and the Hybrids have been there too
[hear the exact moment this hybrid endurance race car switches from electric to gas]

If something is turning like the wheels, you could make it recharge the battery's
That would be the elusive perpetual motion machine. Absent friction, it would work.
They sound like big slot cars
A huge difference from when I watched The Baltimore Grand Prix a few years ago where I had to put in my earplugs over two blocks away 
and provided you could repeal the laws of thermodynamics.

It seems like a good explanation, possibly better combustion with the fuel that is being burned. The amount of fuel was constant, as the pump that feeds the fuel is not adjustable, so I can't see how it burned more fuel.
The one in the video was rather high-tech compared to what we used- an old drywall bucket with a petcock stuck in the bottom. Usually about 30 drips per second was about right, like I mentioned earlier, flame would be shooting out the top of the stove until it got to the point where too much would extinguish it.
...until it gets too big to fit in the engine compartment.
